PVR和PSAD:前列腺癌与良性前列腺增生的鉴别

The clinical value of PVR and PSAD in distinguishing PCa and BPH

目的 探讨前列腺移行区体积 (TZV)与前列腺总体积 (PGV)的比值 ,即 TZV/ PGV=PVR和 PSA密度 (PSAD)鉴别前列腺癌(PCa)与良性前列腺增生 (BPH)的应用价值。方法 采用专用直肠超声探头检测 70例 PCa及 96例 BPH病人的前列腺 PZV及 PGV,并计算其体积比值 ,同时测量血 PSA值 ,计算 PSAD。结果 在 BPH与 PCa两组间 ,PSAD及 PVR有统计学意义 (P<0 .0 1 )。结论 PVR和 PSAD对鉴别 PCa与BPH有较高的应用价值 ,可作为临床前列腺癌的初步筛选指标。

Objective To study the clinical value of PVR and PSAD in distinguishing prostate cancer (PCa) and benign prostate hyperplasia (BPH). Methods TZV, PGV, PVR PSA and PSAD were detected in 70 cases of PCa patients and 96 cases of BPH patients. Results The difference between PSAD and PVR had remarkable significance in both groups of BPH and PCa (P<0.01). Conclusions PVR and PSAD can be the primary screening index in the diagnosis of PCa because of its high clinical value in distinguishing PCa and BPH.
